SPOKESHAVE.

SPECIFICATION forming part of Letters Patent No. 452,498, dated May 19,1891. Application filed May 29, 1890. Serial No. 353,530. (No model.)

To all whom it may concern:

Be it known that I, JOHN F. MAGNUSON, a citizen of Sweden and a residentof New York city, in the county and State ofNeW York, have invented newand useful Improvements in Spokeshaves, of which the following is aspecification.

My invention consists, essentially, in a novel contrivance ofadjustable-handles adapted for holding the tool in different positionsfor facilitating the use of it in various difierent parts and shapes ofthe work, and it also consists in an improved construction for enablingthe tool to be utilized as a corner plane and for the application andadjusting of the guard-cap of the plane hit, all as hereinafter fully described, reference being made to the accompanying drawings, in which-Figure 1 is a plan View of the tool with the handles adjusted about asin the ordinary spokeshave. Fig. 2 is an inside elevation of the frontpart of the stock detached and reversed and with the guard-cap attachedto it. Fig. 3 is an elevation of the back of the plane bit. Fig. 4 is atransverse section of the complete tool on the line as a: of Fig. 1.Fig. 5 is a plan View of the tool with the handles adjusted as for acorner plane. Fig. 6 is a plan view of the tool with the handles as inFig. 5 and inverted and with one of the handles detached to show themode of its connection and adjustment. Fig. 7 is a side elevation of thetool with the handles adjusted as in Fig. 5. Fig. 8 is a front elevationof the back part of the stock with one of the handles detached and withthe other handle in the normal position of the spokeshave-handle. Fig. 9is a transverse section of the stock on line to 10, Figs. 6, 7, and 8,and Fig. 10 is a section of the front. part of the stock on line 3 3Figs. 4 and 5.

I construct the stock in two parts ct and b, the former being whatl callthe back and the latter the front part. The back has the bevel base 0,the'front face cl, the inclined sides 6, and the ear-lugs f. The base 0is that part which slides on the wood, the plane bit q rests on thefront face d, the inclined sides e have the handles t pivoted to them,respectively, and the front part b is secured in the ear-lugs f bypivot-studs t' entering its shoulders j. Said front part also has abevel base 7.: to slide on the wood in advance of the plane-bit, abovewhich is a large openingl for the escape of the shavings, and above theopening, but a little below the pivots t', the guard-cap m is attachedto the under or rear side by the clamp-screwsn in slots of the cap, sothat the cap can be adjusted up or down to gage it with relation to theedge of the plane-bit, said cap hearing all across the bit slightlyabove said edge. The front part b has an upward extension 19 above thepivots 4, through which the clamp-screw 0 is fitted to bear theplane-bit g on the face cl, and at the same time bear the lower edge ofthe guard-cap m on'the lower end of the planebit just above the edge ofsaid bit by the leverage taking effect thereon through the pivots ofsaid front part.

The outer surfaces of the bevel sides e of the backhavepivot-holes sforthehandlestand are faced on the margins q, surrounding said holes, andthe handles are correspondingly faced at u to seat thereon and haveapivot-stud w in the center of the face a, adapted to fit the hole q andbeing tapped in its center to receive the fastening-screw a: from theupper surface of side 6 and having a washer y under its head. The face qis recessed at 2 about a quarter of the circumference of the pivot-holeto provide two stop-shoulders a and b, and the pivot-stud 10 has astop-lug c, which swings between said shoulders and comes to rest onthem, respectively, to stop the handle in its different positions. henthe handles are in the positions represented in Figs. 4:, 5, and 6, saidstop-lugs bear against shoulders a, and when in the positions of Figs. 1and 8 they bear on the shoulders I). The pivotscrews 00 and washers yare to be adjusted so as to bind the handle-pivots with sufficientfriction to cause them to retain their places when set, but allow themto be shifted without difficulty.

In Figs. 4 and 7 it will be seen that the handles have an upward risefrom the pivots to a sufficient height to enable the hand of the user toclear the work while holding the tool, and these are bent at d andproject for the rest of their length about parallel with the base 0 7cof the tool, which bends give the forward pitch of the handles, so thatthey range about in line with the cutting-edge of the bit when adjustedas in Figs. 1 and S, substantially the same as in the ordinaryspokeshave. Another feature of this form of the handles and the inclinedsides 6, to which they are pivoted, is that when shifted to thepositions of Figs. 1 and S the handles, which are preferably about twiceas wide as they are thick, assume the fiatwise positions as thereinshown, in which they are used separately, one in each hand, and in thepositions of Figs. 5 and 6 they turn up edgewise, side by side, andwithin narrower space than the width of the stock, suitably for bothbeing grasped by one hand, in which positions the tool can be usedsubstantially as a corner plane for both right and left hand corners,for which purpose it will be seen that the plane-bit is made as wide asthe stock and is at its edges flush with the edge of the stock-acondition that is made feasible by the contrivanee of the pivoted frontpart of the stock for clamping the bit and by making the upper part ofthe plane-bit narrower, as at e, to extend upward between the ear-lugsby which the front I) is pivoted, said ear-lugs being necessarilylocatedwithin the width of the base 0 7.; and of the cuttingedge of the bit topermit the use of the tool in corners. It will be seen that besides thisadvantage the separate construction and pivoted connection of the frontand back parts of the stock enables the handles to be secured by thescrews inserted from the inside of the back and the guard-cap to beattached by the screws n inserted from the inside of the front in suchmanner that the screws have no objectional exterior projections thatmight interfere with or obstruct in the application of the tool to someshapes of work.

In Figs. 1t and 10 it will be seen that the lower edges of the sides ofthe front I) are beveled downward to the edges 7), so as to make themouth or lower side of the opening I, for the escape of the shavings aswide as the plane-bit and the whole width of the stock, so that theshavings will enter without obstruction, and so as to be forced upwardbetween the said sides, which are of necessity convergent upward toenable the requisite quantity of material for supporting the lower partof front I) to be contained in said sides.

I claim- 1. The combination of the separately-constructed back and frontparts of the stock, pivoted together and provided with the clampscrew,said back having the face for the re ception of the plane-bit, and thefront having the guard-cap attached to the inner side suitably for beingpressed at the lower end on the plane-bit by the clamp-screw, said capbearing all across the bit, substantially as described.

2. The combination of the separately-constructed hack and front parts ofthe stock, pivoted together and provided with the clampscrew, said backhaving the face for the reception of the plane-bit, and the front havingthe guard-cap, said guard-cap and plane bit having equal width andextending flush with the sides of the stock, and the plane bit havingthe narrower upper part extending between the ear-lugs of thepivot-joint of the two parts of the stock, substantially as described.

3. The combination, with the stock having the inclined sides, of handlespivoted to said sides, respectively, and adapted to be set in thelaterally-projecting positions of spokeshave-handles and also in therearwardlyprojecting position side by side, substantially as described.

4. The combination, with the stock having the inclined sides, of thehandles pivoted to said sides, respectively, and adapted to be set inthe laterally-projecting positions of spokeshave-handles and also in therearwardly' projecting position side by side and provided with stopslimiting the movements to said positions, substantially as described.

5. The combination, with the stock having the inclined sides, of thehandles pivoted to said sides by pivot-studs and the handles en teringthe pivot-holes of the sides and secured from the inside of the stock bythe screws, substantially as described.

(3. The combination of the separately-constructed front and back partsof the stock, detaehably pivot-ed together and the handles pivoted tothe inclined sides of the stock and secured by the screws and washersinside of the back and under the front part of the stock.

7. The combination, with the stock having the inclined sides, of thehandles pivoted thereto and having the curved or angular section (1,substantially as described.

8. A spokeshavc-stock made in two separate parts pivoted together andhaving the space for the plane-bit extending the whole width of thestock, and the front part having the opening for the escape of theshavings made the full width of said stock at the lower sides and withupwardly-converging sides, substantially as described.

9. The combination of the separateiy-constructed back and front parts ofthe stock, pivoted together and provided with the clampscrew, and theguard-cap ad ju stably attached to the inner side of the front part bythe slots and fastening-screws, said back part having the face forreception of the plane-bit, substantially as described.

In testimony that I claim the foregoing as my invention I have signed myname, in presence of two witnesses, this 24th day of April, 1890.
